honestly, my first thought was "pull the head out of that big ol' rack and leave the rack at home!"
all those "boosts" and fake "different amp" sims can add up to uneven levels that just mess up the house mix as soon as you engage them. (boosts especially can lead to blown speakers if not contained properly.)
effects can be fun, but there's a lot to be said for dialing in one good tone, letting the sound guy get it balanced in the mix with all the other players, and sticking with it.
(that "good" tone will usually be the one without too much EQ and processing on it.)
